Image Alchemy has the ability to convert between over 90 different raster image formats (including all colorspace and compression variations of each format). Color management features include gamma correction, undercolour removal, seven high quality dithers, colorspace conversion, and palette manipulation. It also includes a Postscript interpreter.
VisIt is an interactive parallel visualization and graphical analysis tool for viewing scientific data. Users can quickly generate visualizations from their data, animate them through time, manipulate them, and save the resulting images for presentations. VisIt contains a rich set of visualization features so that you can view your data in a variety of ways. It can be used to visualize scalar and vector fields defined on two- and three-dimensional (2D and 3D) structured and unstructured meshes. It was designed to interactively handle very large data set sizes in the terascale range, and works well down to small data sets in the kilobyte range.
Mup produces very high quality PostScript printed music or a MIDI file from a text input file. It can handle almost any kind of music, instrumental or vocal, including tablature, shaped notes, guitar grids, alternate tunings, user-defined symbols, and much more. Mup has been under active development since 1992.
Artekopia Netjuke is a cross-platform Web-based audio streaming jukebox powered by PHP 4 and an increasing choice of databases. MP3, Ogg Vorbis, ASF/WMA, and other music file formats are supported. Artekopia Netjuke aims to enable small organizations or communities run a private "mp3.com-like" Web site to access the music they legitimately own, distribute, or are granted access to. It supports most audio players, language packs, optional file downloads, media protection schemes, multi-level security, shared and private playlists, random playlists, images, etc. It also features an unusual, easy-to-use installer module to get you started in minutes.
Q-Midi is a MIDI interface module which allows you to write MIDI applications in the Q programming language. It runs on top of Grame's MidiShare package. Most basic MidiShare functionality is available, including timing functions for realtime programming and MIDI file access. A sample MIDI player application is included (which requires Tcl/Tk).
GImageView is a GTK+ based image viewer. It supports tabbed browsing, thumbnail table views, directory tree views, drag and drop, reading the thumbnail cache of other famous image viewers, and a flexible user interface. It also support movies using the Xine library and MPlayer, and supports images in compressed archive formats like tar.gz, zip, and lha.
Sh is a programming language built on top of C++. It can be used to write shaders that run on top of modern graphics processing units (GPUs), or write stream programs that run on GPUs or CPUs. It is implemented as a C++ library, and allows programs to be generated at run-time using a number of metaprogramming techniques. Variants of programs for different cases can easily be generated, or programs can be generated entirely at run-time from some input data. The system is cleanly separated into a frontend and backend, and is hence portable.
FrAid (Fr[actal] Aid) is a programming language that is appropriate for mathematical computations, visualization, batch processing, and more. It features both a standalone application that provides a programming environment for the language and a system for integrating the language with Java. The Java interface allows mathematical equations and formulas to be used with Java code, making it easier to process numerical computations, symbolic computations, imaging, CAD, and more.
